solar street light manufacturers and high power led

2010 the global LED production value (about ten billion U.S. dollars) to recover almost nearly the TSMC year sales. Many of the large companies will jump into this light sea. The mainland’s foregone layout so that in 2012 the traditional LED battle (Armageddon), and the final victory will be China. China has not only mastered the market, the layout of almost one thousand MOCVD machine the sea, so you can seize the LED lights, in the downstream industries.

The vertical LED production necessary for the soldering of the GaN semiconductor substrate of low inflation, but the chosen low expansion material (such as silicon or GuW of) its poor heat dissipation, thermal expansion of the high thermal conductivity material is much larger than GaN (about 5.5 ppm / mK), the LED experts can not find the ideal convergence materials. This DLC for the interface of diamond and copper composite (diamond heat sink) for the substrate produced the world’s most advanced perpendicular to the LED. This will allow Taiwan’s LED industry to leapfrog ahead of foreign leading companies (such as Nichia, Osram, Lumiled) have taken advantage of to get rid of the patent blockade of Europe, the United States, Japan, Taiwan.

2010 LED tube is used extensively for indoor lighting, outdoor lights and TV backlight. The common incandescent indoor lighting (Incandescent Lamp) and fluorescent (Fluorescent Lamp) is caused by the LCD backlight cold cathode tube (Cold Cathode Fluorescent Lamp) is rapidly be eliminated.

Mainstream LED white lighting, most of the white light are presented in the blue light LED excitation yellow phosphors to generate pseudo-white. The bulk production of the LED are based on a sapphire substrate epitaxial epitaxy growth of GaN LED chip. Growth for the MOCVD (Metal Organic Chemical Vapor Deposition MOCVD). Taiwan has a maximum of MOCVD equipment, first in the country for the World LED die production. But the mainland has to catch up, and even provide the incentives of each the MOCVD grant ten million yuan.

Taiwan, although manufacturing Kingdom for the LED, but like the rest of the foundry industry, LED patent subject to the foreign companies, and each year have to pay large sums of royalties. Money and manufacturing in Taiwan for a foreign boss to make money, but now the production of LED technology has a large number of the relocation of the mainland, which is Taiwan’s LED foundry ecology of sorrow.

After the invention of the LED Street light bulb more than 100 years, advances in lighting technology, lights are also facing a serious threat. In order to achieve the traditional lamp lighting to LED lighting transition (the best led grow light),  Ultra-high brightness LED refers to AlGaInp red, orange, yellow LEDs, GaN-based blue, green, violet and UV LED.

We know that the glow is an energy conversion phenomenon. When the system by external excitation, the lower state transition from stable to unstable energy state. When the system consists of an unstable energy state back to the stable low-energy states.

The structure of the LED Products chips (the best led grow light) of the PN junction electrode and optical systems. When the electrode with a positive bias, electrons and holes were injected into the P and N area, when the non-equilibrium minority carrier and majority carrier recombination, the excess will be the form of a photon energy into light energy. The light emission process consists of three parts: the forward bias carrier injection, combined radiation and energy transfer. Light emitting diodes have many advantages: low operating voltage, low power consumption; stable performance, long life; impact resistance, vibration and strong; light weight, small size and low cost.

Current of the LED light source (the best led grow light) for display and short-range, low-rate optical fiber communication, such as the indicator of a variety of instrumentation, digital and other symbols of the text display. Due to reasons such as brightness and color, LEDs also can not be used for general-purpose lighting, which is the LED future a very important direction of development.

Whether we choose a way to produce white light, if you want to replace the light bulbs, LED lights must be able to offer more light, must have higher energy efficiency. White LED per watt of power consumption can produce dozens of lumens (lighting used to measure light intensity units), the efficiency of incandescent bulbs. White LED is about 10% of electrical energy into light, incandescent bulbs, the conversion efficiency of 7% -8%. However, the white LED is clearly much more expensive than incandescent bulbs.
